Definitions

  • the present invention relates to a safety locking device with tilting hook.
  • Locking devices comprising a housing, a hook mounted in a cantilever fashion for tilting about a tilting axis carried by the housing, and a retractable locking member intended to oppose a tilting movement of the hook when this one is in charge.
  • This type of locking device is used in particular to lock a door or a shutter in the closed position.
  • the locking In certain cases, in particular when the device is used to lock thrust reversing flaps of the engines of an airplane, it is necessary that the locking be provided in a particularly safe manner since a failure of the locking device would have extremely serious consequences.
  • a locking device comprising a housing, a first hook mounted in cantilever on a tilting axis carried by the housing to switch between an open position and a closed position by which the first hook supports a hooking member, and a retractable locking member arranged to oppose a rocking movement of the first hook by pressing a locking part of the first hook on the locking member, the device further comprising a second hook adjacent to the first hook and a connecting member between the first hook and the second hook so that in the closed position of the first hook the second hook is held in a position close to a position in which the second hook supports the 'hooking member.
  • the second hook is immediately put into service and takes over from the first hook to support the hooking member.
  • the locking device comprises a position detector of the hooking member and a position detector of the second hook connected to a control member of the locking member.
  • a position detector of the hooking member and a position detector of the second hook connected to a control member of the locking member.
  • the connecting member is an elastic member disposed between the first and the second hooks to urge the second hook towards a contact with the hooking member when the first hook supports the member hooking
  • the second hook comprises a locking part which is set back from the locking part of the first hook relative to the locking member when the first hook supports the hooking member.
  • the locking part of the second hook has a shape ensuring mechanical blocking of the locking member when it is in contact with the latter.
  • the connecting member is a common support block of which the first hook and the second hook are integral, the second hook comprising a hooking edge recessed with respect to an edge for hooking the first hook and a support part set back relative to a support part for the first hook on the locking member.
  • the first hook and the second hook are made in one piece with the common support block.
  • the second hook is mounted on a tilting axis arranged in a reaction direction of the .second hook when the latter supports the latching member, the second hook is resiliently biased towards a position of contact with the latching member when the first hook is in the closed position, and the connecting member between the first and the second hook comprises a stop carried by the first hook to keep the second hook slightly away from the hooking member when the first hook is in service.
  • the locking device in the first embodiment, comprises a housing 1, a first hook 2 mounted on a tilting axis 3 carried by spacers 4 secured to the housing, and a second hook 5 mounted adjacent to the first hook 2 for tilting around a tilting axis 6 carried by spacers 7 also secured to the housing.
  • first hook 2 and the second hook 5 have almost identical shapes and their outline therefore largely overlaps in FIG. 1 all the more since their tilting axes are coaxial.
  • the first hook 2 and the second hook 5 are mounted cantilevered with respect to their respective pivot axis, that is to say that in the closed position, a hooking member 8 bearing on the hooks tends to tilt these to an open position in which the hooking member 8 escapes from the hooks.
  • the hooking member 8 is for example a hooking rod fixed to a thrust reverser flap 9 by gussets 10.
  • the locking comprises a locking member generally designated at 11 inserted between a locking portion 12 of the hook 2 and a stop 13 carried by the housing.
  • the locking member 11 comprises a control rod 14 mounted to slide in a bore of the housing 1 and comprising a shoulder 15 on which bears a spring 16 which tends to bring the locking member towards an insertion position between the locking part 12 of the hook 2 and the stop 13.
  • the locking member 11 At its end facing the hook 2, the locking member 11 comprises a yoke 17 supporting a locking roller 18.
  • the control rod 14 is connected to a lever 19 hingedly attached to the housing 1 and the housing 1 supports a hydraulic cylinder 20, the rod 21 of which extends opposite the lever 19.
  • the cylinder control 20 is connected by a conduit 22 to a control solenoid valve 23 connected to an electronic control unit (not shown) by an electrical line 24.
  • the first hook 2 is normally returned to an open position by a spring 25 having a end attached to hook 2 and one end attached to housing 1.
  • the first hook 2 and the second hook 5 are associated by a connecting member comprising a helical spring 26 bearing on a tongue 27 secured to the first hook 2 and a tongue 28 secured to the second hook 5 to rotate the hook 2 and the hook 5 in opposite directions so that in the closed position a locking part 29 of the second hook 5 is normally set back from the locking part 12 of the first hook 2 relative to the locking member 11, which further comprises a roller 30 carried by the yoke 17 opposite the locking part 29 of the second hook 5.
  • the locking part 29 has a concave curvilinear shape matching the shape of the roller 30 in order to cause a mechanical blocking of the locking member 11 when the part lock 29 is in contact therewith.
  • the spacing movement of the hook 5 relative to the hook 2 resulting from the action of the spring 26 is limited by the cooperation of a finger 31 carried by the first hook 2 with a slot 32 made in the second hook 5.
  • a lever 33 is mounted on the housing 1 to pivot and has one of its ends in contact with a shoulder 34 of a gusset 10 supporting the hooking member 8, and an opposite end in contact with a position detector 35 connected to the control solenoid valve 23 by a line 36.
  • a position detector 37 of the second hook 5 is also fixed to the housing 1 and extends opposite a edge of the hook 5 comprising a convex profile 38 adjacent to a concave profile 39.
  • the operation of the device according to this embodiment of the invention is as follows: during normal operation, and for a closed position of the reversing flap of the thrust flap 9, the device is in the state shown on Figure 1 that is to say that the locking portion 12 of the first hook 2 is supported on the roller 18 of the locking member 11 and the hook 2 therefore supports the hooking member 8 to hold the flap 9 in the closed position.
  • the second hook 5 is pushed back by the spring 26 in an anti-clockwise direction. This movement is limited by the contact of the hook 5 with the hooking member 8 and in this position the locking part 29 of the hook 5 is slightly separated from the locking roller 30 of the locking member 11.
  • the stop finger 31 is disposed substantially in the middle of the slot 32. The second hook 5 is therefore in contact with the attachment member 8 but does not support the latter.
  • the lever 33 for detecting the position of the latching member 8 bears on the rod of the detector 35 to indicate that the flap 9 is properly closed.
  • the convex part 38 of the edge of the second hook 5 is opposite the position detector 37 and the latter therefore transmits a signal for correct positioning of the second hook 5.
  • the control valve 23 is therefore not inhibited and the withdrawal of the 'locking member 11 can be controlled by line 24 to cause the opening of the locking device.
  • the flap 9 tends to open and drives the hooking member 8.
  • the second hook 5 pivots anticlockwise until its locking part 29 comes into contact with the roller 30 of the locking member 11 which is located then mechanically blocked by the concave shape of the locking part 29.
  • the movement of the hooking member 8 causes the lever 33 to pivot and the detector 35 then sends a signal inhibiting the control valve 23 of the cylinder d opening 20.
  • the second hook 5 breaks while the first hook 2 is in the closed position, the second hook 5 is no longer supported on the hooking member 8 and the remaining part of the hook 5 tends to tilt clockwise under the effect of the spring 26.
  • the concave portion 39 of the edge of the hook 5 then comes opposite the position detector 37 which sends a failure signal from the second hook 5 inhibiting the control valve 23.
  • the first hook 2 is always mounted in a cantilever, that is to say that its tilting axis 3 is offset with respect to the reaction direction of the hook (represented by an arrow), when 'it supports the hooking member 8.
  • the hook 2 comprises, as before, a locking part 12 bearing on the locking roller 18 of the locking member 11.
  • the second hook 5 is this time a self-locking hook, that is to say that the tilting axis 6 is arranged in a reaction direction of the hook when the latter supports the hooking member.
  • the second hook further comprises a concave support surface 40 for receiving the hooking member 8.
  • the second hook 5 is connected to the locking member 11 by a telescopic rod 41 having one end fixed to the second hook 5 and one end fixed to the locking member 11, and urged in a direction of extension by a spring 42.
  • the offset between the first hook 2 and the second hook 5 is limited by a stop 43 carried by the first hook 2 and extending in a curvilinear slot 44 produced in the second hook 5.
  • the relative position of the stop 43 and of the slot 44 is determined so that in the closed position illustrated in FIG. 3 and when the stop 43 is at the bottom of the slot 44, the concave support surface 40 of the second hook 5 is slightly set back relative to the member hanging 8.
  • this second embodiment is as follows: in the normal position of use illustrated in FIG. 3, the hooking member 8 is supported by the first hook 2. If the latter or its tilting axis is broken , the hooking member 8 comes to bear on the second hook 5 which supports it and simultaneously ensures mechanical locking of the locking member 11. If the second hook 5 breaks, the spring 42 tends to pivot the part remaining hook 5 which is no longer retained by the positioning finger 43 and the detector 37 sends an inhibition signal from the control valve 23.
  • the operation of the control jack 20 causes the locking member 11 to be withdrawn, which in turn causes the second hook 5 to retract.
  • the first hook 2 switches in the usual way towards the open position under the effect of the hooking member 8 and the return spring 25.
  • FIGS 4 to 6 illustrate an alternative embodiment of the device of Figure 1. To simplify the explanations, only the locking hooks have been shown as well as the second hook rupture detector.
  • first hook 2 and the second hook 5 are carried by a common support block 45 with which they are preferably made in one piece, for example by machining a metal block.
  • the common support block 45 is mounted to tilt about a tilting axis 3.
  • the first hook 2 has a locking part 12 bearing on the locking roller 30 when the hook is loaded, that is to say say when a fastening member 8 is in abutment on a fastening edge 46 of the hook 2. In this position which is shown in the figures, the fastening member 8 is immobilized and therefore retains the object to which he is associated.
  • the second hook has a hooking edge 47 which is set back from the hooking edge 46 of the first hook.
  • the second hook further comprises a support part 29 on the locking roller 30 which is also set back relative to the support part 12 of the first hook.
  • the rupture detector 37 of the second hook bears on the latter at any point on the edge of the second hook. Indeed, if the second hook breaks while it is not loaded, the break will take place in the narrowest part, that is to say at the connection with the common support block 45. The broken hook will fall and detector 37 will report this regardless of its position along the edge of the hook.
  • the hooking member 8 will bear on the edge 47 of the second hook and will rotate the latter until the bearing part 29 comes into contact with the roller 30. The device will then blocked in the locked position as in the case of FIG. 1.
  • the offset between the edges 46 and 47 on the one hand and the parts 12 and 29 on the other hand could be very small to keep the second hook unloaded as long as the first hook is in service.
  • the invention is not limited to the embodiment described and it is possible to make variant embodiments without departing from the scope of the invention.
  • the device according to the invention has been shown with a locking member mounted to slide, the invention can be carried out by providing a pivoting locking member.
  • the two hooks can also be attached to the common support block 45 instead of making them in one piece with the latter.
